18 Amazing Facts About Your Body That Explain a Lot

For centuries, the human body was a subject of studies and experiments and even inspired inventions like cameras and the Eiffel Tower which was inspired by the thigh bone. And you would think that throughout history there would be no secrets left to uncover, but this list will prove you wrong.

We at Bright Side find every aspect of human beings to be fascinating — from their kindness and compassion to the simple structure of an eye. That being said, we’re excited to share some interesting facts about the human body with you.

1. The human body can survive a lightning strike.

9 out of 10 people who were ever struck by lightning have survived the encounter. It doesn’t even depend on the state of a person’s body since the survivors’ ages range from children to people in their 50s.

2. A toothache and a headache are linked together.

Have you ever noticed that your toothache is linked to your headache? You’re not just imagining things — thanks to the trigeminal nerve that goes through your jaw to your head, those 2 pains usually go hand in hand.

3. The human brain can be more active during sleep.

Stages of the human sleep process were discovered in the 1950s and according to findings, our brains are busier when asleep than when awake.

4. We’re the only animal who can blush.

As a psychological or physical response to our environment, blushing can be perceived as cute and we are proud to say that humans are the only creatures on Earth that can do it!

5. Our brains can’t feel pain, but they take up a quarter of the body’s oxygen.

Our brain, as powerful as it is, possesses no nerve endings that would register pain or damage to it. However, for it to function, it takes up to 25% of all the oxygen your body gets.

6. Facial hair is the fastest growing hair on your body.

If you ever ask the male population about this, they will agree that they have to “face this fact” every day when they have to shave. It’s probably good that a lot of women find bearded guys attractive, right?

7. The nail on your middle finger grows faster than your other nails.

It may be inconvenient for your manicure upkeep, but it’s absolutely true: the middle fingernail grows the fastest.

11. The acid in your stomach can melt down metal.

Can you imagine if you were carrying around a pouch of extremely powerful acid at all times? Well, you are! We’d never suggest trying this on your own stomach but just know this: it can dissolve metal over time.

14. The first trimester of pregnancy brings weird dreams.

Isn’t it peculiar, that during the early stages of pregnancy, women dream of frogs, worms, and potted plants? This could have an interesting meaning psychologically or have no meaning at all — but can’t we agree that pregnant ladies go through enough as it is?

17. Growing older with less taste

Remember when olives were the worst food ever? If now they seem like a good pairing with a bunch of other foods with sharp tastes, it is because over time with the aging process we’re losing taste bud sensitivity and by the age of 60, people usually lose up to 40% of their sense of taste.
